Delving into taxonomy – in the marine realm

I’ve recently had the opportunity to expand my academic horizons by assisting a Ph.D. student (who has now completed his degree!) with statistical analysis of morphological data from two purported species of New Zealand brachiopods, which are shelled marine animals in their own phylum that is closely related to the molluscs. Though we were unable to statistically distinguish the species based on morphometrics, enzyme analysis indicated that they should remain separated. Moreover, we confirmed that morphological differences between brachiopod species in other genera range from very small to quite large. It’s been quite a novel experience for this plant community ecologist to have a hand in taxonomic research, and on marine animals at that!
